Pediasure — found a plastic piece in the pediasure powder chocolate flavour

I would like to inform you the following for your kind perusal and immediate action that I am using pediasure for my son from past 1 years regularly. I bought a box of Pediasure from a medical shop near my area.
Batch No - 01031MN1
Packed on - 02 / 02 / 2019
Expiry Date - 16 / 07 / 2020

Today on 7th June 2019 I opened the pediasure box to make a frink for my son and I discovered a plastic piece in the powder. This is the very first time I have discovered something like that in the pediasure chocolate flavour powder and was shocked by seeing the plastic piece inside the pack. I was willing to lodge a complaint to the consumer court and other civic authorities but before that I though of mailing it to you. Their are tons of people buying this product for their kids and if something like this is ingested by the kids unknowingly it can cause major health problems and I think you should be concerned about it. Being a mother of a three year old I really want to hear from your side about the complaint mentioned above and I kindly request you to take necessary action regarding this.

Thanking you
